Picolight Preps Parallel Push
Just this week, Picolight announced the OEngine family of subcomponents, piece-parts used in optical transmitters and receivers. Picolight also celebrated shipments of a transceiver based on a 1310nm Vertical Cavity Surface Emitting Lasers (VCSELs), although it's said the VCSELs in that case are based on another company's technology (see PicoLight Debuts Laser Family and Picolight Ships 1310nm VCSELs).
But wait, there's more! Vice president of marketing Warner Andrews says Picolight will be announcing parallel receiver arrays for the 1310nm spectrum in a week or two.
Details are scarce, but the idea probably involves packing multiple receivers into one integrated device. Integration usually yields benefits such as smaller size and lower power consumption, which in turn allows for higher-density systems.
Receiver arrays would be useful in a variety of "listening" applications, such as multiwavelength performance monitoring, Anders says.
What about corresponding transmitter arrays? It's been done aplenty at 850nm, with 12-channel VCSEL arrays having been produced by Picolight -- as well as Agilent Technologies Inc. (NYSE: A), Corona Optical Systems Inc., Emcore Corp. (Nasdaq: EMKR), Infineon Technologies AG (NYSE/Frankfurt: IFX), and Zarlink Semiconductor Inc. (NYSE/Toronto: ZL), to name a few. You've also got TeraConnect Inc. and Xanoptix Inc. integrating multiple dozens of VCSELs, although TeraConnect appears to have called it quits (see TeraConnect Inc. and Xanoptix's Strange Story).
But for 1310nm, Picolight is content to offer its receiver array first, with VCSEL integration to come later. "Array transmitters, that's something that will probably come online in 2004," Andrews says.
One company that already produced 1310nm VCSEL arrays was Cielo Communications, which was acquired by Optical Communication Products Inc. (OCPI) (Nasdaq: OCPI) last year (see Cielo Announces VCSEL Modules and OCPI Acquires Cielo). OCPI, which seems to have activated the Cone of Silence since the acquisition, hasn't publicly announced its plans for that product line.
